Confused Kinkster

I work at a small retail store and my days are long and exhausting. But when I get home, the real me comes out, kinky and craving more than just casual fun. Last week, during a kinky meetup, things got intense quick. A stranger tied me up in the back of their car as if it were no big deal. I was so turned on but also terrified. Was this normal? Should I feel guilty for enjoying being controlled like that? What should I do next time to stay safe and still have my kinks fulfilled? Am I just crazy or is this something others experience too?
